(CNN) - GOP hopeful Michele Bachmann said Wednesday that a recent episode at a book signing, in which a young boy told her his gay mother "didn't need fixing," was "reprehensible."
"He obviously didn't want to say what he was put up to say, and I just think it's reprehensible when someone uses a little child to advance a political agenda," Bachmann said Wednesday on CNN's "John King, USA."
"That's what was going on in a book signing. I'd never do that to one of my children, and it's really unfortunate that this poor, little boy was used in that way."
The incident, which was recorded and has since received millions of views on YouTube, took place at a bookstore in South Carolina. The Minnesota congresswoman said it was clear the boy's mother goaded him into speaking to her.
In the interview Wednesday, Bachmann stood firm in her opposition to same sex marriage.
"I'm very unashamed, I believe that we should all be allowed to have our opinions respected, and I stand for marriage and marriage between a man and a woman," Bachmann said.
As for the current GOP frontrunner Newt Gingrich, Bachmann said the former House speaker had distracted voters from his record using finely-tuned language.
"He's very good at co-opting the conservative language, and he's using that conservative language, but his record completely belies his language," Bachmann said. "No one has been more the epitome of a Washington, D.C., insider than Newt Gingrich. He's taken over $100 million for influence peddling in Washington, D.C. His office is located on the Rodeo Drive of Washington which is K Street, and he's taken over $1.6 million to influence senior Republicans to keep the big mess at Freddie Mac going."
Bachmann continued, listing a host of issues she disagreed with Gingrich on.
"He's wrong on immigration, he's wrong on global warming, he was wrong on the $700 billion bailout, he was wrong on Libya. On issue after issue, his positions have hardly been conservative. He's had more in common with Barack Obama than he has with our conservatives. That's not what we can have for our nominee."
